Disconnections at roughly 6:30pm each evening

Hiwanted to post this before raising a potential ticket, how can i see connection/disconnections on the technicolor router. previously i could look at a log.want to check if there is a pattern of disconnections at roughly the stated above time. when we first picked the fibre connection it was solid as a rock, but recently it's been dropping out quite regularlyEDIT: Nuneaton exchange here.Edit2: error message presented by router was "idle timeout reached" and "concentrator not reachable" after that at bang on half 8.
